METHOD OF INTRODUCING A STEAM JET To A WATERGAS-GENIYKKWF'RVFUEL'BED.

Application filed September 1?. 1921.

To all um; um i" may m'mwrn:

Bo ii known that i. loin S. llAI'fl. n ciii zen of (hi l'nituil Emil-s. residing at lhiln' dolphin, in ihc vomit i l Philadelphia and State of Pennsylvania. haw inwnlvrl a now and IlSPl' IJl Ucthml of lnfnri'lucing n. Strain vlil to n lvllmkliii-(i(ll{'2ll0! Fuel Iitil, of which lhc following is 21. spcrilicalion.

It is prr'scnt common practice to supply steam in IL straight How or line jet, admitted from the wall oftlio gencrzitor top space. and this slraighl jcl of steam impinges cithcr upon the fuel bed or izpon 'the wall of the enerator and is' dispersed at either one of tnese points mid ilisitrihutc Isnl'f more or less rhrouglioni tlngencriitor op Hpncc. The impact of such 1: straight ja i or simian: of steam is, however. wry hoavyanil if it inipinges upon thelop of flue fu l sit-am will be forced in very heavy quantity through ihe fuel at llic. particular point of impact which results in LKCESSiVG cooling of that. part of the. fuel and also in poor decomposition of the very heavy quantity of swam forced through the fuel at this point. if the straight jet. of steam impinges on the Wall of the set there will ho heavy cooling and n wearing cli'ect or eroding upon the brick lining.

The principal object of the prnscnt invcntion is to obviate lhc above llllflllflllid \lPfP tS and disnrlvanti-lgus and to olfcct an iiuprnvnment'jn the supply of steam to \viitor gas generators wlicrz-hy tho impact of a ('UTMQH- traled and vcry high vi-locily jct of Fllillll with either tliv Fuel boil or the wall of (he set is provintwl. AnnLlit'l' objvct of the invention is to intruduco tlnswam in rlillusuil and cxpaiulwl form uniformly in he vntirc surface of the Fuel l'itfl whornby \vzilr-r vntrained in thc strain is l'lililill i'vnvz p rullml. and the stoam adv- 1ntugnnunlv applicd.

()ihor objects ol lhc iuvrniion will appcfir from thc following (inscription and this in volition may be said to consint in ihr mvlhoal of introdui-ing :1 strain ji't in Lliilnsuil anrl cxpanderl form and uniformly to (he lfllilf: surface of a water gas g 'nvralor fn l lit-(l which consists in imparting i1 rotatory motion to the jet by discharging il lnngvntially upon a curverl surface before it: strikr-s the fuel berl. and this can be ilnno cithcr internally or externally of the gr-ncmtnr wall as will fully appear from the following cxplana tion.

'lhc invention also comprises the improve mom to be presentlydescribed and finally claimed.

In tho l'nlloiviug description reference will be illilililti] the :urvompanying drawing form ing part hir-of and in which Figure l a diagrammatic vertical secliunnl view illustrative of apparatus by means of whirl: the invention can be practiced when rotatory motion is imparted to the jct outside of the generator Wall.

Fig. 2 is a svctional view drawn in an enlarged scnhand illustrating in elevation this curved wall shown in Figure 1.

Fig. 3 is a horizontal section on lines 3-5 ("If 2. i,

Fig. 4 is n vertical SPCfiiis-fifil view of apparatus by means of which the invention can be prnctici-(l when rotatory mot-ion is im art- Prl to the jet inside of the generator 'wal or, morc spi-cilil-nlly, in the coal hole branch at the top of the generator.

Fig. 5 is H horizontal sm-iiona] View of the same drawn to an enlarged scale, and

Fig. i is a horizontal sectional view of appnrnlus in; moans of which the invention (on he prai'ticerl when rotary motion is im- Ilill'llfl to the jul inside of the gcncrator wall.

llvfvii'ing to Figs. l-3. the si'i-am jet enterin; at 1. is give-n :i roinlory motion in a pm-hilly shaml filling 2 which is shown in lliow liguri-s and which may ha described as mirhifoi'iii prior to its discharge into the gcnci'zilor. this rotatory motion being of mun-1w prrsvrvvel or pcrsisted in after the rntry of the steam info the. generator. In tho lilting :2 {ho jcl of'slcnm is discharged fangi-niiallv upon thr- I.liIVP(l Wall 3 before it s! rikrs llK i'uvl lwrl and in fact lwfore it colors the gcnnrni'or chamber. Referring to Figs. 4 :in 'l f. thv int. of steam in rlinchargcd hingci'itially nlonp lhc innrr surfacc of the coal holo lflflllfl? 4 of which the innor surface 5 is curved. Referring to Fi 6. the 'el of slcazn is discharged tangentia lly alongl a genm'nlor wall (1' which is curved.

The invention is more especially applicable to tho su plying of steam to the to of the in making a down run but it. might he applied to the supplying of steam to the bottom of a generator fuel bod. Howc m'. as stated. if is m re applicable to the top of the fuel bed. among other reasons became a rose or spray nozzle or device at the top of l upward.

the fuel bed would undoubtedly burn ofi partly at least because the air blast is always In the description use has been made of the term steam jet but the invention applies equally well ifche term air jet be substituted for the term steam jet because the invention really consists in the described method of introducing a fluid jet to a water s generator fuel bed and in fact both ds of jets are em loyed', and the invention is applicable to botli.

It will be obvious to those skilled in the art to which the invention relates that modificatiohs may he made in details of procedure withoq t departing from the spirit of the inventiofi which is not limited as to suvh mat- MIB or otherwise than Sis the prior art and the appended claims in ay require.

mangoes ing it tangentially upon and along a curved 25 surface before it strikes the fuel bed, substantinlly as described.

2. The method of introducing a'tluid jet in diffused form and uniformly to the entire surfave of a water gas generator fuel hed \Ylllt'll consists in imparting u rotatory motion to the jet hy discharging it tangentially upon and along: a curved sin-fave be fore it strikes the fuel lied. HllllStnIltiflll as described.
